Title: Improvements in paint mixing and grinding machines
IPC: B02C7/06
Filed: 1936-02-25
Abstract: 451,643. Roller-and-breast mills; disc mills. RUCKER, J., 1229, Zalabi, Dvur KralovÚ n. Lab., Czecho Slovakia. Feb. 25, 1936, No. 5621. [Class 59] A paint mixing and grinding machine comprises a pair of toothed, intermeshing mixing wheels 1, 2, Fig. 3, rotatably mounted in concaves under a hopper 4 and adapted to receive material from the latter, the wheel 2 being slotted at 8 between the teeth and connected to a hollow shaft 6 forming a conduit for the material, a non-rotatable plunger 9 in the shaft being operative in one position to close the slots and in another position to close the conduit by a disc 12 on an extension 11 of the plunger so that the material will be returned through the slots to the hopper. A grinding disc 14 is carried by the plunger at the end of the conduit and a sieve structure 16 mounted on the shaft 6 encloses the grinding disc and co-operates therewith. The plunger 9 is connected by a lever 10 to a weighted arm and the disc 14 is slotted to allow the paint around the hollow shaft to pass to the rotatable disc 16 which is perforated and covered on both sides with screens, a rubber roller 20 carried by a collecting ring 19 being pressed against the outer sieve by a weighted lever 21. If the pressure on the grinding disc is excessive the plunger 9 is forced back and material is returned to the hopper through the slots 8.

Title: Stringed musical instrument
IPC: G10D3/08
Filed: 1943-04-08
Abstract: 568,392. Stringed musical instruments. McBRIDE, J. W. April 8, 1943, No. 5640. [Class 88 (ii)] In a stringed musical instrument the stopping which determines the free length of the string is effected by contact with a helically-ribbed rod 37 arranged parallel to the string and rotated by one of a set of press-buttons 33 ... 36 projecting laterally from the neck 2. Each button 33, Fig. 9, of the guitar shown in Fig. 1 is formed with a shank slidable in guides and having a rack 51 for engagement with a pinion on the corresponding rod. The helices may be simple or multiple, continuous or interrupted, and of constant or varying pitch. They may be provided with damping inserts of resilient material which may be terminal or intermediate, and transversely or longitudinally arranged. The buttons are pressed against the action of springs surrounding a reduced portion of each rod. They are calibrated to correspond with similar markings on the rods, the calibrations 86 being visible through a cylindrical lens in the cover 75. To make the pressure on the string uniform the rods are made of greater diameter adjacent to the middle parts of the string than at the ends adjoining the points of attachment. The body of the instrument may enclose a sound-amplifying unit connected to a variable resistance 91 controlled either from a thumb-button 107 by the side of the press-button 36 or by a lever 99 protruding beneath the peg-board 3.

Abstract: 608,462. Electroplating-apparatus. LUCAS, Ltd., J., SILMAN, H., and STEIN, W. Feb. 25, 1946, No. 5768. [Class 41] A work-piece carrier, for use in electrodeposition of metals on hollow metal work - pieces which are open at one side, has a pivoted member adapted for the attachment of the work-piece thereto in such a manner that the work-piece when immersed has the open side uppermost, the member being counterbalanced at least in part by one or more floats, and on withdrawal of the carrier from the bath the member is tilted so that liquid in the work-piece is emptied into the bath. As shown, the carrier comprises a bracket b extending from a suspensory cathode member c and provided with a rotatable spindle d to the ends of which are secured arms e carrying floats f. A flexible spring wire ring h adapted to grip the interior of a workpiece a is secured to a collar g on the spindle d. The work-piece a when taken out of the bath is in the position shown, but when it is immersed the floats act to tilt it to a position where the open side of the work-piece is uppermost and the work-piece is filled with liquid. The angular movement of the spindle d is limited by stops i<1> on a member i secured to the bracket b.

Title: Improvements in or relating to switching systems for the electric lighting installation of mechanically propelled vehicles
IPC: B60Q1/46
Filed: 1961-02-17
Abstract: 915,605. Electromagnetic relays. BOSCH G.m.b.H., ROBERT. Feb. 17, 1961 [Feb. 19, 1960], No. 5933/61. Class 38 (5). [Also in Group XXXV] An, electromagnetic relay comprises an insulating disc 34 carrying a contact bridge 16 which shorts contacts 40, 41 in its inoperative and contacts 42, 43 in its operative state. Energizing an electromagnetic coil 30 causes a flexible switching-rod to move against a restoring force to engage a recess 37 and thus turn the disc 34 about a pivot 33 and against the action of a spring 39 into the operative position. Interruption of the current through the coil 30 causes the rod 31 to withdraw and the disc 34 to return to its original position under the action of spring 39. If coil 30 is energized together with a second electromagnetic coil 35, then on the movement of the disc 34, an armature 36 is attracted by the coil 35 so that the operative position of the disc 34 is maintained against the action of the spring 39, when the coil 30 is de-energized. Further energization of the coil 30 causes the rod 31 to engage a second recess 38 on the disc 34, thus returning it to the original position against the action of the stillenergized coil 35.

Abstract: 711,693. Winch clutches. PRIESTMAN BROS. Ltd. Feb. 15, 1951 [March 9, 1950], No. 5984/50. Class 78 (5) A grab crane is provided with two winding drums 1, 5 of equal diameter intended respectively for the closing and hoisting and for the opening and holding ropes and being mounted in line so that they may rotate independently of each other about the same axis, and a clutch 15 to connect the winding drums directly together so that they may be rotated together at the same speed about the said axis. Twin drums 1 (Fig. 1), freely mounted on shaft 3 are driven from motor 7 though chain 8, pinion 9 and spur wheel 10 secured to drums 1. Drums 5 and 6 secured to shaft 3 are driven from motor 11 through chain 12, pinion 13 and spur wheel 14 fixed to drum 5. Drums 1 and 5 may be interconnected through clutch 15. To shaft 3 (Fig. 2) is keyed spider 21 which carries clutch band 16 embracing extension 18 of drum 1, one end of said clutch band being pivoted at 20 to said spider and the other end of said clutch band being adjustably secured at 23 to arm 24, and said arm 24 being pivoted at 25 to the spider and being rigidly connected to arm 26 which is resiliently biassed at 27 and forms the means of operating the clutch band Arm 26, in turn, is operated by a foot pedal or solenoid 46 through crank arm 45, shaft 44. arm 43 and brake band 40, the latter being fixed at 41 and passing round brake drum 39, and the latter drum being freely rotatable on shaft 3 and carrying opposite lugs 36, 37 which operate said arm 26 through pin-and-slot means. Thus solenoid or pedal 46 causes brake band 40 to slow down brake drum 39 rotating with spider 21 at the speed of shaft 3. This relative rotation between brake drum and spider causes movement of lugs 36, 37 to swing arm 26 clockwise about 25 so that the clutch band. 16, usually slack, is tightened and drums 1 are clutched to shaft 3 and therefore to drums 5 and 6. In this way all four drums .are driven from either motor. Spider 21 is formed with adjustable pads which locate the clutch band. Specifications 264,327, [Class 80 (ii)], and 536,952 are referred to.

[Class 42 (ii)] [See also Group IX] The presence of pieces of string formed of cotton, jute, hemp and like vegetable fibres in wool and other animal fibres or fabrics is detected by treating the fibres or fabrics with a solution of a chemical that will cause the string to appear luminous and different from the wool fibres when exposed to artificial-light, exposing the treated fibres to such light and while so exposed separating the string therefrom. The fibres are treated with a weak solution of Primuline, Mimoza Z or Thioflavine S (respectively numbered 812, 813 and 816 in the Colour Index) and then exposed to the light of a mercury arc, nickel cobalt tube. The string then appears different from the animal fibres and can be readily detected and removed.
